Benefits of technology
The cartridge provides a cost-effective, secure, and high-capacity storage solution for mobile devices, allowing for large data storage in a compact form, addressing the limitations of existing portable media solutions and enabling a more robust entertainment experience on mobile devices.
Problems solved by technology
At present, however, the entertainment experience is limited, even primitive, compared to what consumers have come to expect from their game consoles, home theaters and DVD-equipped computers.
The main problem is data storage.
The fact is that sophisticated digital entertainment is data-intensive, and it is growing more so every day.
Traditional small “form factor,” portable media such as CompactFlash® cards, SD flash cards, Memory Stick™ and other solid state memory devices simply cannot deliver the capacity and price per megabyte required for a high-quality entertainment experience.
Recording content onto solid state memory cards in high volume is expensive and impractical, and securing that content effectively is very difficult.
While some experts predict that broadband Internet access will deliver high-quality games and movies to mobile consumer electronics devices, there are significant barriers to success.
Cell phone networks are designed to transmit voice communications and are simply not efficient for high-capacity data transmission.
Cell connections are not capable of the required speeds and are notoriously unreliable, with frequent dead zones and dropped connections.
While games are being delivered to cell phones currently, the quality of game play and the game environment cannot begin to approach that of a console.
Nonetheless, managing streaming and interactive content such as multiplayer games and high-quality video or movies for thousands, if not millions, of users simultaneously will be challenging for any network.
Security is also a problem for WiFi, leaving content providers open to potential pirating activities.
Moreover, the data storage problem would still exist.
Perhaps the most significant problem for networked content delivery is cost.
It has been estimated that it can cost more than $30 to send a DVD-quality film over the Internet.

Embodiment Construction
[0056]FIGS. 1A and 1B show perspective views of a cartridge 10 according to this invention. Included in both views are an insert 102, which is preferably made of plastic, and a sheath 104, which is made of sheet metal, preferably stainless steel. Insert 102 will be referred to as a “plastic insert” herein, although it will be understood that insert 102 could be made of other materials, such as metals, ceramics, linen phenolic, wood, composite materials, compressed paper or other fibers. FIG. 1A shows the top side of cartridge 10, and FIG. 1B shows the bottom side of cartridge 10. FIGS. 2A and 2B are top and bottom plan views of cartridge 10, respectively. Also visible in these views are a shutter opening 106, a shutter 108, and a spindle opening 110. As shown in FIG. 2A, a recess 193 is formed in cartridge 10. Recess 193 interacts with a mechanism on the drive to retain cartridge 10 in the drive after it has been inserted into the drive. Recess 193 is also shown in FIGS. 10A and 10B...

Abstract
A cartridge for an optical data storage disc includes a monolithic shell and a sheet metal cover plate. The shell includes lateral walls and a floor that together define a cavity that holds an optical data storage disc. The cover plate is attached to the shell, with the cover plate abutting the top surfaces of the lateral walls of the shell. The optical disc is housed in the disc cavity, with the data side of the disc facing the cover plate. A sheet metal shutter is wrapped around an edge of the cartridge and is slideable between an open position, wherein a portion of the optical disc is exposed through a shutter window in the cover plate and a closed position wherein the shutter overlies the shutter window. The cartridge is very strong and is easy to fabricate. The use of sheet metal next to the data side of the optical disc allows the data on the disc to be read or recorded with a very short wavelength laser.
